. Claims. (01. 299 144) This invention relates to irrigating apparatus and particularly to a sprinkler head type thereof adapted for use beneath low growing plants for This condition is aggravated by the fact that in such installations the water is at most from the head.

With these considerations in mind it is an object of the present invention to provide a sprinticularly adapted for use for under plants and in locations where irrigation is desired over limited areas.

Fig. 5 is a transverse sectional View of the cap component of the sprinkler head taken on the line 5-5 of Fig. 3,

Fig, 6 is a perspective view of a portion of a sprinkler system embodying a sprinkler head is less than a full circle, and

tion between the outlet bore 4 and the inlet bore 3 of the body member.

The body member I externally of the outlet bore 4 is provided with a reduced diameter, externally threaded portion I which terminates in an an- The cap element 2 is formed from the same size of bar stock as the body I and is provided with or 01f of the body member and which thus regu-z lates the amount of water allowed to flow through the port. When desired, the cap can be screwed on the body sufliciently to enable the valve element to completely shut off the flow. The side walls of the cap are provided with a plurality of- 4). It is particularly to be noted in Figs. 4, 5 and. 7 that each oi the outlet ports I! is of greater.

cross sectional area than the inlet port it and 7 that therefore the velocity of projection of water that maximum velocity and consequent distance of projection of the discharged water is intentionally inhibited.

Assuming that a system has been installed, the various cap elements are then adjusted to give the desired amount or rates of flow and the system is ready for service; In some instances as along a walk W or alongside a building or wall the full circle of water distribution is not needed or is to be avoided. For such locations (see Fig. 6) a cap [2 which is identical with the'cap element 2 except for having fewer, outlet ports and having a porticn of the periphery without ports is employed. In making the adjustment of such sprinkler caps to regulate the now, the cap is adjusted until the desired rate of flow is achieved without regard for the direction of the ports in cident to such adjustment. The body element is then turned on the nipple N or the nipple itself is screwed into or out of the T by which it is connected to the main until the ports are in the desired radial position. While the illustrated'modification shows four ports, it will be understood that the number of ports and the angle between them or other angular position may be varied to suit each special situation.

' While in the foregoing specification I have described. and illustrated certain. embodiments of my invention, I do not intend thereby to limitmyself to the exact forms thus disclosed, and the invention is intended to embrace all such modifications in the parts, and in the construction,

combination, and arrangement of parts as shall come within the purview of the appended claims.

I claim:

1. In a sprinkler type irrigating device, a body member having an internally threaded bore at one end affording means of attachment to a source of water supply, an outlet bore disposed in axial alignment with said inlet bore at the opposite end of said body member, an inlet port in said body member disposed in axial alignment with said bores and affording communication between said bores, a cap mounted on said body member and closing the outer end of said outlet bore and movable to infinitely variable fixed positions axially of said port; said cap having a plurality of discharge ports extending from the interior to the exterior thereof; and means formed integrally with said cap operable in response to axial movement of said cap relative to said body member to prevent the fiow of water through said first-named port or to vary the flow therethrough from said outlet bore supply to said outlet bore' and said discharge ports; the combined cross section-areas of said discharge ports being more than twice the cross sectional area of said inlet port.

2. In a sprinkler type irrigating device, a body member having axially aligned inlet and outlet bores formed in opposite ends thereof; said inlet end being adapted for attachment to a source of water supply, an inlet port in said body member disposed in axial alignment with said bores and aifordingcommunication between said bores, a

cap mounted on said body member and closing the outer end of said outlet bore; said cap having internal threads engaging corresponding threads 75 member disposed coaxially with respect to'saidj on the exterior of said body member, means carried by said cap and movable therewith axially .of said body member toward and away from said bores extending toward each other from opposite ends of said body member with the bottoms of said bores forming a wall therebetween and with the inletbcre being internally threaded for connection to a source of water supply, a port of lesserdiameter than said bores extending-throughsaid wall and disposed in axial alignment with said bores, an external thread on said body member. disposed coaxially with said outlet bore, an internally threaded cap member engaging said external thread and having a valve member movable therewith to infinitely variable fixed extents to ward and away from said port as said cap is turned on said threaded engagement and effective thereby to vary the rate of flow of water through said port, and a plurality of radially disposed discharge ports of greater capacity than said inlet port extending through said cap member effective to dis tribute water entering said outlet bore through. said first-named port to an area surrounding and' disposed beneath said device at a reduced pressure and velocity.

In an irrigating device, a body member having axially aligned inlet and outlet bores formed in the opposite ends thereof; said inlet bore lee-- ing internally threaded for connection with asource of water supply and the inner ends of said bores forming a conical wall between the bores,- disposed with the apex thereof extending intothe outlet bore, an inlet port disposed in axial alignment with said bores extending through saidwall and having an outlet orifice at the apexof saidwall, a thread on the exterior of said body member disposed coaxially with respect to said outlet.

bore, a cap member closing the outer end of said outlet bore and comprising an end wall portion and an internally threaded side wall portion threadedly engaging the threads on said body member, and a valve element carried by and ex tending into said outlet bore and movable to infinitely variable fixed extents toward and away from said outlet orifice incident to movement of said cap member on said threads to vary the flow of water through said port, and a discharge port of greater cross sectional area than the cross sectional area of said inlet port extending through said side wall portion of said cap member.

conical bottom surface with the apex thereof directed toward the outer end of said bore, an inlet port disposed in axial alignment with said outlet; bore extending through the apex of said bottom surface affording communication between. said inlet bore and combining with said conical bot tom surface to form an annular ridge aboutsaid port, an externally threaded portion on said body 5 outlet bore, an annular wall of lesser external said cap member and sai diameter than said externally threaded portion vent or to variably perm and having an internally threadedside wall por- HOWARD E.
